CONTROLLING AND CUT-OFF VALVE FOR STEAM-LINES.

To all whom it may concern Be it knownthat I, JOHN A. GOLLIHER, acitizen of the United States, residing at Fulton, in the county ofFulton and State of Kentucky, have invented new and useful Improvementsin Controlling and Cut-Off Valves for Steam-Lines, of which thefollowing is a specification.

This invention relates to a controlling and cut-ofi' valve for steamlines, and particularly to a valve of this character adapted for use onthe steam lines of railwaycars.

One object of the invention is to provide a valve, of the characterdescribed which is simple of construction and may be easily andconveniently repaired. 1

Another object of the invention is to provide a valve which may beemployed for blowingofi the steam line, to discharge the water ofcondensation.

Another object of the invention is to provide a valve which may bereadily and conveniently adjusted from either the platform or side ofthe car.

Another object of the invention is to provide a valve which whenarranged" at the rear of a train can be adjusted to cut-off position,and when arranged at the head of a train may be employed for blowing outthe steam line from the head end, so that the responsibility for suchwork may be placed upon a single attendant, such as the fireman of theengine.

A still further object of the invention is to provide a safety valvewhich may be applied at each end of a car, so that the valve upon, anycar in the length of a trainrmay be employed to blow off the water ofcondensation from both ends, without liability of the train men beingscalded, as is liable to happen in detaching hose couplings for thepurpose.

A still further ob ect of the invention 1s to provide a valve which, ifgenerally employed, will reduce delays and avoid liability of thefreezing of pipes in cold weather, by allowing the steam line of a trainto be drawn off or drained in a ready and expeditious manner. l I y Theinvention consists of the features of construction, combination andarrangement of parts herein fully described and claimed, reference beinghad to the accompanying drawings in which Figure 1 is a top plan view ofa combined controlling blow-off valve embodying my in- Specification ofLetters Patent.

Application filed May 9, 1914. Serial No. 837,539.

vention. Fig. 2 is a side elevation of the same. Figs. 3, 4 and 5 arehorizontal longitudinal sections, showing the valve in cutoff, serviceand blow-out positions, respectively. Fig. 6 is a vertical transversesection through the valve casing. Fig. 7 is a vertical longitudinalsection thereof. Figs. 8 and 9 are detail views of the valve and thevalve stem. Fig. 10 is a view of the operating handle.

Referring to the drawings, 1 designates the valve casing, which isprovided with an inlet end 2 internally threaded for connection with thetrain line pipe and having an angular head 3 for the application of awrench, whereby it may be conveniently screwed on and off. Between itsend portions the casing is formed with a vertical valve cavity orchamber 4: to receive a rotary plug valve 5. The chamber is closed atits lower end, as shown at 6, and open and internally threaded at itsupper vend, as shown at 7. A threaded plug 8 is adapted to fit withinthe threaded upper end 7 of the valve cavity and is formed with a headedor flanged upper end 9 to engage a bearing rim 10 upon the casing, saidplug being provided with a socket 11 to receive an angular wrench head,so that it may be easily applied and removed.

The inlet end of the valve casing is formed with an inlet channel 12which is divided by a partition 13 into side channels 1 1 and 15, whichside or branch channels connect the inlet channel with the valve cavity.The opposite or outlet end of the valve casing is formed with a )air ofoutlet or discharge channels 16 and 1 in respective alinement with thebranch channels 1-1 and 15, said channels 16. and 17 terminating inouter threaded ends 18 for communication with hose pipes or nipples towhich the hose pipes are attached. A partition 19 separates the outletchannels 16 and 17 from each other and its side walls 20 divergeoutwardly from the valve cavity, for a purpose hereinafter described.

A valve 5 is formed with a pair of cavities or recesses 21 and 22,arranged in the sides thereof at substantially an angle of 90 withrelation to each other, the cavity 21 beingof somewhat greaterdimensions than the cavity 22. The valve is adapted when arranged in thecut-off position shown in Fig. 3 to blank both passages 16 and 17 andthus cut as the flow of steam. When turned to the position shown in Fig.4:, the cavity 21 connects the inlet channel 12 with the outlet channel16, while the cavity 22 connects the two outlet channels, together, thusproviding for the flow of the steam through both outlet channels.

munication between the inlet channel 12 and the outlet channel 17, andopens up direct and exclusive communication between the channel 12 andchannel 16 for the blowing out of the steam and water of condensationfrom the train line. The valve is provided with a longitudinal passage23, intersecting at'its lower end an angular socket 24, and through thispassage 23 and a corresponding passage 25 in the plug 8 extends a valvestem 25. The lower end of the stem is formed with an angular head 26which fits within the countersink or opening 24, while the upper end ofthe stem terminates in a head 27 and an angular end port on 28' formedwith a perforation to receive a cotter pin 29. The

head 26 fitting within the recess2t, couples the valve to the valve stemfor turning movement, as will be readily understood. A double valve,handle is provided for adjusting the. valve, said handle comprising abody portion 30 slotted to engage the angular end 28 of the stem andadapted to be held in position thereon by the cotter pin 29, andfromtsaid body portion 80 extend handle members or levers 31 and. 32arranged, at

i also fol-cutting. oh the flow of steam from coach to coach asconditions may require. The valve at the rear end of the coach of atrain will, of course, be maintained in. blank position, to prevent theescape of, steam at that point. By the use of the valve in the mannerdescribed upon the coaches of a train it, is evident that the pipesmaybe blown out for the discharge of the-water of condensation at desiredintervals, or by sim- .ply opening a valve at the center of the theengine, may be held responsible, thus insuring greater efficiency andreliability of control. The valves enable a train line to be i When thevalve is turned to the position shown in Fig. 5, it cuts oil commenscalding themselves, as is apt to happen in uncoupling hose connectlonsfor blow out purposes. a

It will be observed that by the use of the V'-shaped partition 13, thesides of which diverge in the direction of flow of the fluid, the columnof fluid entering through the inlet 2 is divided into two columns ofsubstantially equal pressures which, through the passages let and 15,exert substantially equal pressures on the valve 5, thus distributingthe pressures so. as to prevent the valve from binding. It will also benoted that the walls of the partition 19 diverge toward the outlet endsof the passages 17 and 18, thus tapering and constricting said passages,whereby free flow of the fluid into said passages through the cavitiesin the valve is insured, so that in the event of the arrangement of thevalve as shown in Fig. i an eflicient flow of steam to the passage 17via the cavity 21', passage 16 n cavity 22Wi11 obtain I claiml:

1. A valve of the character described comprising a casing having aninlet at one side and a pair 0t outlets atits diametrically oppositeside, and arotary plug valve in said casing. having cavities ofrelatively difierent sizes in its sides at a right angle to each other,said cavities being so arranged that by adjusting'the valve toja certainposition communication between the inlet and outlet ports will be cutoff, by adjusting the, valve to a, second position communicatio may beestablished between the inlet and one of the. outlets, and by adjustingthe valve to a third position communication maybe establishedbetween theinlet. and the other outlet.

2. A, valve of the character described com: prising a, casing having avertical valve chamber, aninlet at one side of said chamber, outlets atthe other side of thechamber, partition dividing the inner portion ofthe inlet into branch, passages, a partition separating the outlets fromeach other, a

notary valve in said chamber having side cavities arranged at a rightangle to each other, 01163016 said cavities being of greater size thanthe othergsaidj valve being adjustable to. one position to cut oilcommunication between the inlet and outlets, to a second position toestablish communication between one of the branchpassages and one of theoutlets through the valve cavity of larger size, while simultaneouslyestablishing. communicationbetween the outlets through, the valve cavityof smaller size,

prising a casing having an inlet at one end and a pair of longitudinallyextending outlet passages at its opposite end, a valve chamber betweensaid inlet and outlet passages and a rotary valve mounted in saidchamber to control said passages, said valve having cavities in itssides at. right angles to each other, said cavities being so arrangedthat the valve when turned to one position 4. A valve of the characterdescribed having an inlet at one end, longitudinally extending outletpassages at its opposite end, and an intervening valve chamber, a V-shaped partition separating the inlet end into two divisions; apartition separating the outlet passages and formed to constrict saidpassages in a discharge direction, and a rotary valve arranged in saidvalve chamber and provided with ports at right angles to each other forcooperation with said inlet and passages.
